During heavy rain, when is there a risk of aquaplaning?
Aquaplaning happens when a film of water lifts the tyres off the road; the primary trigger is speed: at high speed even good tyres can’t evacuate enough water and you lose steering and braking.
- Speed: the faster you go, the higher the risk; slow down early in heavy rain.
- Water depth & ruts: standing water and wheel tracks make lift-off more likely.
- Tyre condition/pressure: worn tread or wrong pressure lowers the aquaplaning threshold.
- Prevention: reduce speed, avoid puddles, steer smoothly, and keep tyres in good condition.
